Question
Write the remainder when the polynomial $f(x)=x^3+x^2-3 x+2$ is divided by $x+1$.
✓
Answer
When the polynomial $f(x)$, divided by $(x+1)$ the remainder will be
$f(-1)=(-1)^3+(-1)^2-3(-1)+2$
$=-1+1+3+2$
$=5$
Thus, the reminder $=5$
$f(-1)=(-1)^3+(-1)^2-3(-1)+2$
$=-1+1+3+2$
$=5$
Thus, the reminder $=5$
